Hardboard helps make a very good foundation for your mosaics as extended as you limit the measurement of the total mosaic, limit the tesserae dimension, and don’t exhibit the mosaic in a wet setting. Stay away from hardboard for outdoor applications since of the potential for deterioration. Assuming your tesserae are the dimension of a quarter or significantly less and the total dimensions of your mosaic is significantly less than 24″x24″, I have identified that 1/eight-inch thick hardboard offers an adequate basis. If your tesserae are modest, it truly is surprising how adaptable the mosaic is, even with grout, which signifies it can face up to some warping prior to the grout cracks or glass parts pop off. If your tesserae are massive or if you include big items of stained glass into your mosaic, the thickness of your foundation must be greater because the mosaic cannot endure as significantly warping (i.e., the thicker the wood, the more resistant to warping). For instance, suppose your mosaic is 24″x24″ and you use a solitary piece of yellow stained glass to represent the bright solar lighting up the entire world. Suppose the sun’s diameter is 10 inches, which helps make up a excellent chunk of the mosaic. It truly is simple to see how a tiny warping can tension that one piece of glass triggering failure (i.e., breaking, popping off). It really is like ceramic tile on a concrete-slab foundation. As the concrete cracks and moves, anxiety is utilized to the ceramic tile and, if the tension is fantastic sufficient, the tile breaks. As a result, you must consider the tesserae dimension when choosing the thickness of your mosaic’s basis.
Above the several years producing a lot of wall mosaics that are 24″x24″ or less, I have located that my favourite basis is one/eight-inch hardboard. It really is the dark-brown things that pegboard is created from but without the holes. It really is slippery easy on 1 side and tough on the other. I use this substance only for dry, indoor, wall mosaics that will not be exposed to moisture. I use this materials since it is: 1) Reasonably slender, 2) Reasonably lightweight, and three) Tough on one side so the glue grabs hold of it well.
The 1/8-inch thickness permits the finished mosaic to fit in a regular pre-produced body. My glass tesserae are about one/eight-inch thick, so the complete thickness of the concluded mosaic is only about 1/four-inch. This makes it possible for me to purchase a all set-made frame for practically practically nothing. create photo mosaic to be sixteen”x24″, eighteen”x24″, or 24″x24″, which are common measurements for pre-manufactured frames. If I were to use three/four-inch plywood or MDF as the foundation, I would then have to use a custom body with sufficient depth to cover the whole thickness of the mosaic (i.e., 3/4-inch wooden foundation in addition 1/eight-inch tesserae equals practically a one-inch thickness). Custom made frames cost up to five times more than regular pre-created frames. For example, by using advantage of their biweekly fifty% sale at my favorite passion shop, I can get a pre-produced eighteen”x24″ body in a wonderful type and color that best fits the mosaic, have the mosaic mounted in the frame, have the hanging wire set up, and have paper backing installed, all for considerably less than $25. That’s appropriate! Considerably less than 25 bucks. A customized-created body might cost as considerably as $150.
Not only do I preserve on framing fees, the hardboard is cheap when compared to three/four-inch plywood and MDF. I buy a pre-cut part of hardboard as an alternative of a full 4’x’8 sheet. The pre-cut segment is 24″x48″. Knowing the height of my indoor wall mosaics is normally 24″ (which is the width of the pre-cut segment), this allows me to reduce the hardboard providing me a 16″, eighteen”, or 24″ width for my mosaic foundation. For example, suppose I want my mosaic to be eighteen”x24″. The pre-lower width of the hardboard I buy is 24″. I measure and cut eighteen”, which results in a piece of hardboard that is eighteen”x24″. The piece matches flawlessly in a common eighteen”x24″ pre-created frame. I measure and minimize the hardboard employing a standard round noticed and a “rip fence” that I make by clamping a 3-foot degree to the hardboard with two C-clamps. The rip fence allows me to press the saw alongside the straight edge of the amount to make certain a straight and correct reduce.
I put together the hardboard foundation by painting it with two coats of white primer. The primary cause for painting it white is to get a white history onto which the glass tesserae will be adhered (Note: I often adhere the glass to the tough facet of the hardboard). Despite the fact that I typically use opaque glass, the white background helps brighten it up. The dark-brown color of the hardboard tends to make the glass pieces look boring and dark, even although the glass is intended to be opaque. The secondary reward of painting the hardboard with primer is that it seals it. I will not know if sealing hardboard does anything, but it tends to make me really feel much better believing it’s sealed. I never know the material or chemical qualities of hardboard and how it’s created, so I will not know if it requirements to be sealed, but painting it gives me a nice, warm-and-fuzzy experience. I have a practice of sealing every little thing regardless of whether it demands it or not.
Following applying the tesserae and grout, you’ll be surprised at how versatile the mosaic is without creating glass or grout failure (assuming your tesserae are comparatively small). When I first utilized 1/8-inch hardboard as the foundation for a mosaic, I experimented and discovered that I could bend the mosaic a complete two inches without having affecting the glass and grout. I was way too frightened to bend it far more than two inches! Right after the experiment, I assumed if the mosaic can bend a whopping two inches, then it can endure any warping that may well take place. Then, right after the mosaic was mounted in the pre-produced frame, I recognized that the mosaic was installed in this sort of a method to inhibit any warping at all. The mosaic was pressed and held in-place with the small fasteners in the back of the body to preserve it from slipping out. The only way the mosaic can warp is if it is sturdy sufficient to lead to the frame to warp with it. I’ve never ever experienced a issue with any indoor wall mosaic warping when using one/eight-inch hardboard set up in a regular pre-made body.
one/eight-inch hardboard is also lightweight enough so the bodyweight of the overall mosaic is not so hefty that you have to remodel your house to create a assist structure stout ample to keep the fat of a mosaic. Typically, my 24″x24″ (or considerably less) mosaics are light sufficient to sufficiently hang by implies of a picture hook and nail set up in drywall. I never have to minimize into the drywall to set up 2″x4″ items between the studs and then change the drywall. This is very useful, specifically when promoting or providing absent the mosaic (i.e., you will not get rid of buyers that you may well otherwise shed if you notify them they have to dangle the mosaic by doing some thing much more than pounding a nail into wall).
